thickening without flocculants

UNDERSTANDING POLYMER FOR THICKENING AND

coagulants or flocculants is necessary for efficient separation by clarification, decanting, sedimentation, filtration, thickening, and dewatering processes. • The terms “coagulant” and “flocculant” are often used interchangeably; however, they are not the same (see Figure 2).

Thickening Resource Book

Thickening Definition Continuous thickening by an operation called sedimentation is the separation of suspended solid particles from a liquid stream by gravity settling. The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants.

Next generation polymeric flocculants for thickening and

rheology modifying agents, or thickening agents, that has significantly improved the overall efficiency of this process (Berger et al., 2011). Commonly used rheology modifiers (also known as flocculants) are very high molecular weight water soluble polymers. These polymeric flocculants improve the thickener

Flocculants an overview ScienceDirect Topics

Most commercial flocculants are synthetic water soluble polymers with average molecular weights in the region 1000 to 30 × 10 6.They are generally supplied as powders that have a limited storage life, particularly when made up into solution. While there is an understandable reluctance for manufacturers to divulge their exact chemical nature, it is known that the majority of polymer
